Once a work address has been added in a new state and a new employee has been hired and assigned a work address in that state, you can get registration assistance in Gusto.
Pricing varies by state—get started below and during step 4, you'll review the price, process, and estimated timeline to completion.

Q: Can I run payroll for my employees before my registration is complete?
A: Not in most cases—you typically need to have a withholding account number and required tax rate(s) in Gusto before you can run payroll.
If you’re registering in a state where there is no income tax withheld, you can use the state-specific “new employer rate” in this article until you receive your company-assigned rate from the agency.
Q: Can I use Gusto to register in a new state if I don't have a Federal Employer Identification Number (FEIN) yet, or if the business is undergoing a merger or acquisition?
A: No–you must have a FEIN entered in Gusto to order a state tax registration.
If your company is going through a merger or being acquired, CorpNet cannot assist with registration. Work with your tax advisor and state agencies directly to navigate this change and register your business.
Q: Where can I see all my tax information?
A: You can see all tax details in the following locations:
Gusto’s state tax registration service does not contain tax, legal, financial, or HR advice. Since rules and regulations change over time and can vary by location, consult a lawyer, HR expert, or accountant for specific guidance.

A: In order for CorpNet to start the registration process for an unemployment account number before you're liable, you can:
Q: Can I register with CorpNet if the responsible party is based internationally and does not have an ITIN/SSN?
A: CorpNet may be able to assist directly—reach out to [email protected] or call 1(888) 449-2638.
Q: My company is a nonprofit—why can't I enter 0% in the responsible party section, or add a commercial owner?
A: Some states have a 1% minimum for the responsible party ownership percentage. Those states are: ID, KS, MN, OH, SC, DC, DE, MD, NJ, NY, and RI. Registration orders will need to be placed directly through CorpNet, outside of Gusto, or you'll need to register directly with the agency yourself.
Some states require that an individual owner be listed on the account. If you're a non-profit and not sure how to proceed, contact CorpNet directly at [email protected] or call 1(888) 449-2638.
Q: Does CorpNet help with state tax account closures?
A: No—you'll need to close the tax account on your own.

Tax payment rounding
MO requires that all income tax payments be rounded to the nearest dollar. Here’s how that’s handled based on whether we have to round up or down.
